Nomenclature

The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

  • AGROECOMYRMEX [Agroecomyrmecinae]
    • Agroecomyrmex Wheeler, W.M. 1910a: 265. Type-species: †Myrmica duisburgi, by original designation.
    • [†Agroecomyrmex also described as new by Wheeler, W.M. 1915h: 56.]

Wheeler (1910) first proposed this genus to place a Baltic amber fossil described by Mayr:

Lachnomyrmex seems to be related to Apsychomyrmex, Calyptomyrmex and Agroecomyrmex gen. nov., to which I refer the peculiar Myrmica duisburgi (= Agroecomyrmex duisburgi ) described by Mayr from the Baltic amber. The differences between Lachnomyrmex and Apsychomyrmex will be readily appreciated by comparison of Figs. 2 and 3. Calyptomyrmex and Agroecomyrmex both have deep antenna I scrobes above the eyes, but the former differs from Lachnomyrmex in having ll-jointed antennae, an unarmed thorax and a very different type of pilosity; while Agroecomyrmex does not have a 2-jointed antennal club, the eyes are near the posterior corners of the head and the tip of the gaster is directed forward as in the Ponerine genera Proceratium, Sysphincta, Bradoponera, Discothyrea and Alfaria.
